We report on a search for gravitational waves from binary black hole inspirals in the data from the second science run of the LIGO interferometers. The search focused on binary systems with component masses between 3 and 20M. Optimally oriented binaries with distances up to 1 Mpc could be detected with efficiency of at least 90%. We found no events that(More)
Two new rare pyrane-based cembranoids, sarcotrocheliol acetate (1) and sarcotrocheliol (2), along with two known cembranoids, cembrene-C (3) and sarcophine (4), and the aromadendrene sesquiterpenoid, palustrol (5), were isolated from the soft coral Sarcophyton trocheliophorum. Chemical structures were determined on the basis of extensive analysis of their(More)
Multiple feedback systems are foreseen to ensure stable luminosity for the X-band linear collider. Beam-based train-by-train steering feedbacks will be used in the linac and at the IP. Active stabilization of the final doublet is being developed to counteract the possibility of excessive vibration from the detector. Another option is fast intra-train(More)
For 17 days in August and September 2002, the LIGO and GEO interferometer gravitational wave detectors were operated in coincidence to produce their first data for scientific analysis. Although the detectors were still far from their design sensitivity levels, the data can be used to place better upper limits on the flux of gravitational waves incident on(More)
